Dolphins are not fish, but warm-blooded animals. They live in groups, and speak to each other in their own language. In this way they are like other animals, such as bees and birds. But dolphins are very different from almost all land animals. Their brain is nearly the same size as our own, and they live a long time --- at least twenty or thirty years.

Like some animals, dolphins use sound to help them find their way around. They also use these sounds to talk to each other and to help them find food. We now know they do not use their ears to receive these sounds, but the lower part of the mouth, called the jaw.

Strangely, dolphins seem to like man, and for thousands of years there have been stories about the dolphin and its friendship with people.

There is a story about sailors in the 19th century. In a dangerous part of the sea off the coast of New Zealand, they learnt to look for a dolphin called Jack. From 1871 to 1903 Jack met every boat in the area and showed it the way. Then in 1903 a passenger on a boat called The Penguin shot and wounded Jack. He recovered and for nine years more continued to guide all ships through the area－except for The Penguin.

Today, some people continue to kill dolphins, but many countries of the world now protect them and in these places it is against the law to kill them.

Dolphins are interesting animals and researchers find them interesting to watch. They don’t have hands, but can use tools to solve problems, just like us. Scientists have observed a dolphin trying to get a shy eel(鳝鱼) to come out of its hole by poking(捅)it with a dead fish. Many species of dolphin live in large societies. They have many different relationships and need a good communication system; they use a variety of sounds to communicate with each other.

There is currently no evidence that dolphins have a language of their own. But scientists still have a lot to find out about these animals and so there are certain to be a few surprises in the future.

At Kewalo Basin Marine Laboratory in Hawaii, the dolphin team have developed a sign langue to communicate with the dolphins, and the results are amazing. Not only do the dolphins understand the meaning of individual words, they also understand the significance of word order in a sentence. For example, when they were asked to ‘touch the ball with your tail and then jump over it’ they generally responded correctly and straight away, which showed that they understood the langue.

Most mammals seem to enjoy play—but dolphins seems to like making their games as challenging as possible. On a beautiful day in 1997, researchers working at a beach, off the southern coast of Brazil, observed a little dog going into the sea and swimming towards the dolphins. To their surprise, the dolphins approached the dog and then started throwing it into the air. The dog seemed to enjoy the ‘game’ and continued playing with the dolphins for more than an hour. From then on, different dogs were seem trying to interact with the dolphins.

Dolphins live in a very different world to ourselves, but they are very good at our ‘intelligence tests’. For example, they will jump out of the water when they hear a whistle noise. They do this because they will get a fish as a reward. There is still much to learn about these flexible(灵活的)problem-solvers, but from the evidence so far, it would seem as though dolphins are very intelligent.

1.To get a shy eel to come out of its hole , a dolphin would poke it with____.

2.At a laboratory in Hawaii, the dolphin team have developed a ____ to communicate with the dolphins.

3.Dolphins not only understand the meaning of individual words, they also understand the importance of ______ in a sentence.

4.When they play, dolphins seems to like making their games as ______ as possible.

5.Dolphins will jump out of the water when they hear a whistle noise in order to _______.

Dinosaurs now are far away from us. Dinosaurs were real animals that once lived on the earth, but they _1_ (die) out about 65 million years ago. The _2_(disappear) of the dinosaurs is _3_ some way a great mystery. Some scientists think that the climate changed suddenly. Fossils of trees tell us that the temperature dropped a lot and that the level of the sea dropped as well. This means that it got suddenly much _4_ (cold). Perhaps the dinosaurs were too slow __5__(change) with the climate. A new idea is _6_ a meteor(流星) crashed into the earth. Scientists discovered a place in Mexico _7_ they think the meteor crashed. They think that there was a lot of dust from the meteor. The dust landed on the plants. Also the dust blocked(阻挡)the sun’s light for as long as five years.

Animals seem to have the sense to eat when they are hungry and they do not eat more than their bodies need. It has been shown that rats will, when given a choice over a period of time, prefer water with vitamins(维生素) to water without vitamins even though there is no difference in taste or smell between the two water bottles. When a fragrant flavor was added to the vitamins-enriched water, the rats did seem to develop it and kept drinking it, even after the vitamins were switched to the clear water. In time, however, they broke the habit and went back to where the necessary vitamins were.

In a classic experiment, babies of 6 to 12 months old were placed in a cafeteria feeding arrangement, with a wide selection of baby food before them. They were given whatever food they pointed to or appeared interested in. We are told that at first they showed some unusual eating patterns, but over a period of time they managed to select well-balanced diet.

So, in choosing food, rats and babies do seem to know and act on what’s best for them. Apparently, there is a kind of “body wisdom”, which humans soon lose. Most of us do not eat as wisely as we could. Many of our food preferences are culturally determined and influenced by long-formed habits. Some people eat foxes, dogs and blackbirds, while we eat cows and pigs. So what people eat and how much they eat seems to be greatly influenced by what is going on around them.

1.In the experiment on rats, a fragrant flavor was added to the rats’ drinking water to _________.

A. test whether rats know which drink is good for them

B. encourage rats to drink vitamins-enriched water

C. find out rats’ preference in flavor

D. demonstrate the vitamins are tasteless

2.According to the passage, adults eating habits differ from those of babies because _________.

A. adults know better than babies what kind of food are good for their health

B. adults’ eating habits are closely related to the social and cultural customs

C. adults have more choices of food than babies in eating patterns

D. adults usually cannot resist the temptation of various delicious foods

3.As far as their eating habits are concerned, babies and rats are similar in that ________.

A. both prefer flavored food and drink

B. both have the same eating patterns

C. both have the wisdom to choose a balanced diet

D. both develop a taste for the same kinds of flavors

Imagine you are in a jumping contest. Animals and insects can also enter this contest. But they might just leave humans in the dust!

The first event is the long jump. The human athlete is Mike Powell. In 1991, he jumped nearly 30 feet, which is the world record for the long jump. That is about five times his own height.

His competitor in the long-jump contest is a frog named “Rosie the Ribbiter.” Rosie set the world record for frogs in 1986 by jumping more than 21 feet. Her record has never been broken by any other frog. Compared to Mike Powell, Rosie’s jump is not that amazing. But wait! Rosie is only about 10 inches long when her legs are stretched to their full length. She can jump more than 25 times her size. Rosie, the frog, wins the long-jump event.

The next event is the high jump. Javier Sotomayor, the world record holder, can jump a bar (横杆) 8 feet high. That is about as high as the ceiling in most homes.

Looking around for someone to challenge his record, Javier might need a magnifying glass (放大镜). The next contestant is a tiny insect called the spittlebug (吹沫虫).

The spittlebug can jump 28 inches into the air. It is only a quarter-inch long, less than the width of a pencil. If the spittlebug were the same size as Javier, it would be able to jump 600 feet into the air. That is like a human jumping over a building 55 stories high!

Though the humans lose the “jumping contest,” their competitors would probably agree that Mike and Javier are still pretty excellent athletes. If only Rosie and the spittlebug could speak!

1.The underlined word “contestant” in Paragraph 5 means “_____”.

A. coach            B. teammate            C. challenger        D. record holder

2.What can we learn about the spittlebug?

A. It likes living on the ceiling.

B. It is good at flying in the air.

C. It is the same length as a pencil.

D. It has a wonderful jumping talent.

3.In the author’s opinion, Rosie and the spittlebug’s jumping abilities are ________.

A. surprising        B. promising        C. doubtful            D. fearful

4.How does the author develop the text?

A. By giving instructions.

B. By making comparisons.

C. By following the order of time.

D. By following the order of importance.

高一英语阅读理解中等难度题查看答案及解析

We know that many animals do not stay in one place. Birds, fish and other animals move from one place to another at a certain time. They move for different reasons: most of them move to find food more easily, but others move to get away from places that are too crowded.

When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration(迁移) is probably the migration of the fish, which is called the “salmon”. This fish is born in fresh water but it travels many miles to salt water. There it spends most of its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies there. In northern Europe, there is a kind of mice that leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed by falling into the sea.

Recently, scientists have studied the migration of a kind of lobsters(龙虾). Every year, when the season of bad weather arrives, lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody knows where they go.

So, sometimes we know why humans and animals move from one place to another, but at other times we don’t. Maybe living things just like to travel.

1. Most animals move from one place to another at a certain time to ____.

A give birth            B enjoy a warm climate

C find food more easily  D find beautiful places

2. The fish called “salmon” spends most of its time in ____.

3. A kind of mice in northern Europe move when ____.

A they give birth               B the weather becomes bad

C there are too many of them in one place  D they haven’t enough food

4. What is the main idea of the passage?

A Animals move in order to find food more easily

B The migration of the fish called “salmon” is the most famous migration

C Living things move from one place to another because they like to travel

D Sometimes we know why and how living things move from one place to another, but sometimes we don’t.
